S PARK-ARRESTER.

SIEGIFIGATION forming part of Letters Patent No. 435,177, dated August-26, 1890.

Application filed December 31, 1889. Serial No. 335,483: (No model.)

had therein to the accompanying drawing.

This invention relates to certain new and useful lmprovements in spark-arresters; and

p it has for its object to provide a simple and efficient spark-arrester of few parts and provided with a spark-receiver readily detached for the purpose of cleaning or otherwise. 7

The novelty resides in the peculiarities of construction and combinations, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the drawing, and then particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawing, which is a central vertical section through my improved sparkarrester.

Referring to the drawing by letter, A designates a shell, which may be of any desired shape, but preferably in the form of an inverted truncated cone, provided'at its lower end with a neck or collar A for attachment to the smoke-stackin the'usual manner. The upper end of this shell A is formed with an annular neck port-ion A and this shell is provided interiorly with a cylindrical wall B, ar ranged parallel with this cylindrical portion and attached to the tapering walls of the shell, as shown, forming an annular chamber B near the upper end of the shell. Depending from this annular chamber is a tube 0, the lower end of which is designed to extend within the spark-receiver D, which has at its.

u pper end an opening to receive the same, said upper end being conical, as shown, and reticulated, as shown at C. This spark-receiver D is designed to be detachably connected in position, and this may be accomplished in any suitable manner, preferably,however, in the manner shown, whereinE is a bar or support extending from the portion A laterally and having a right-angled portion E, the lower end of the receiver D being provided with a depending arm D, attached at its upper end and free at its lower end, as shown, and designed to fit over the portion E of the bar E, as shown in the drawing, and firmly support the receiver in place. When it is desired to remove the receiver for the purpose of cleaning or for any other purpose, it is simply raised until the arm D is disengaged from the portion E and the receiver rotated partially so as to bring the arm. D

away from the arm E, when the receiver may be readily removed.

F is the top having an annular depending flange F and an annular flange F This top is' curved outward, as shown at F", to provide an annular space above the Wall B, said top being in the form of a ring, from the inner annular edge of which depends a reticulated cone G, which may be of suitable wire-gauze or perforated metal. This reticulated inverted cone allows of the ready escape of the steam and smoke, and the steam kills the sparks which are blown into the space or chamber B, from whence they are drawn through the tube 0 into the spark-receptacle D.

The device is simple, of few parts, durable, and in practice has proved very efficient.

That I claim as new is- 1. The combination, with the shell and its inner annular wall B, forming the annular chamber B, of the spark-receptacle removably supported upon an arm extending from the shell and having reticulated upper end, and the tube 0, communicating with the annular chamber and passing through said reticulated end into the receptacle, substan- ALBERT M. HARRIS.
